Thermogravimetric Analysis

Thermal Analysis of Polymers, Polymer Composites, and Elastomers.

Stress Engineering Services provides Thermogravimetric Analysis (TGA) for thermal analysis of polymers, polymer based composites and elastomers. TGA can be used to determine the kinetics of decomposition of a material, the distillation temperature of a liquid, the effect of aging and medical sterilization, and the effect of prolonged exposure at static temperatures.

It is a valuable technique when used to analyze the organic/inorganic composition of a material. Samples can be as little as 1 mg. TGA testing can occur in various gaseous environments (Nitrogen, Oxygen, Air, etc.). Our expert engineering staff conducts analysis using both standardized and customized methodology.

Standard Tests:

ASTM E1131: Compositional Analysis via TGA

ASTM D6370: Elastomer Composition Analysis via TGA

ASTM D2584: Ignition Loss of Cured Reinforced Resins

ASTM D6558: CO₂ Reactivity of Anode/Cathode Blocks

ASTM D3850: Rapid Degradation of Electrical Composition

ASTM D6375: Evaporation Loss of Lubricating Oils
